Question 4
Consider a system with U(t) as input and V(t) as output
Choose the correct option
Question 5
A continuous time signal x(t) = cosω0t is sampled with sampling interval Ts generating the discrete time sequence
If x(n) is periodic with period N and r is any positive integer, then Ts must satisfy the relation.
